COMZPANY, OF CHICAGO, ILLINOIS,

ELINOIS, ASSIGOB TO PETTEBONE IULLIKEN A.' CORPORATION OF DELA-WARE A BUTMENT-gEQUIPPED BOD My'invention relates to rods provided with abutments thereon, serving, more especlally as stop means, as for vexample 1n spring switch constructions and my object, enerally stated, is to provide a novel, simp e and inexpensive construction of abutment means which may be quickly and economically assembled with a rod and be held thereon against accidental displacement.

Referring to the accompanying drawings, in which I have illustrated my invention as embodied in an labutment-equipped forming an element of a spring switch Figure 1 is a longitudinal sectional view of such a switch mechanism in which my invention is embodied.

Figure 2 is a view in longitudinal section shwing the detail ofthe abutment-equipped ro Figure 3 is a face view of one ofthe parts of the device of Fig. 2.

Referring to the particular construction shownwthe switch mechanism is of the same construction as that shown in my pending application for United States Letters Patent Serial No. 271,884, filed April 21, 1928, and therefore a general description thereof will suffice.

The switch mechanism shown comprises a cylinder 6 for liquid, as for example oil, adapted at-its end portion 7 for connection with a bar (not shown) connecting the switchpoints together. Slidable lengthwise in the cylinder 6 is a rod 8 adapted for connection at its end 9 with a switch-stand (not shown). In the particular construction shown the switchpoints may be set to cooperate with either of the main rails at which it is located, such setting being effected by manipulating the switch-stand. l

Slidably mounted on the inner end of the rod 8 between abutments 10 thereon, are pistons 11 with a co'l spring 12 interposed rod a similar view of a sectionall Application iled Iaroh 8, 1929. Serial No. 344,861.

between, and abutting at its ends against, these pistons.

In one set pos'tion of the switch-stand one I of the pistons 11 engages with one end of the cylinder forming a stop therefor and the other piston is enga ed by the adjacent abutment device 10, wit the spring 12 in compressed condition and the switchpoints set against one of the main rails of the track for holding this Switchpoint yieldingly in such position and permitting of the trailing of the wheels therethrough in the movement of a train from the switch track to the main track.

In the other set position of the switchstand the last-reerred-to piston abuts against the other end of the cylinder 6 andthe other abutment 10 engages the other piston placing the spring under compression in which position of the parts the other Switchpoint is yieldingly pressed against the other main rail permitting of trailing throu h.

The abutments 10 on the rod 8 are constructed in accordance with my invention and as the are of the same construction the description will be limited to one thereof.

The abutment 10 is formed of a pair of substantially semicircular ring sections 13 positioned in an annular groove 14 in the rod 8, and a ring 15 surrounding the rod 8 and the sections 13 as shown in Fig. 2 holds the lat' The ring 15 is provided with ter in place.

extending ange 16, intimately an inwardly embracing the periphery of the rod which limits outward movement of the ring 15 on the rod 8, the flange-equipped end of the ring 10 opposing the portion of the piston 11 with which it cooperates in performing the abutment function.

The ring 10 is held in place suiliiently tightl to prevent accidental dis lacement romt eringsections13. Thismay eeii'ected by making a driving fit between the ring 10 and the ring sections 13, but preferably the end of the ring opposite that provided with the flange 15 extends beyond the adjacent end 'of lt e ring 13 and is deiiected inwardly into overlapping relationship to the ring as shown at 17, as for example by peening it over against the end of the ring sections 13.

In Fig. 5 I have illustrated by dotted lines the form of the terminal end portion of the ring 15 before assembly with the ring sec tions 13 and the rod 8, and by full lines the position to which this end of the ring is deiiected as stated.

Thile I have illustrated and described a particular construction embodying my invention, I do not Wish to be understood asinltending to limit it thereto as the same may be modiied and altered without departing from the spirit of my invention.

lVhat I claim as new, and desire to secure by Letters Patent, is:

An abutment-equipped rod structure comprising a rod having a peripheral recess, a split ring disposed in said recess projecting outwardly beyond the latter, a ring surrounding said split ring and holding the same in said recess, the second mentioned ring having a flange at one end adapted for direct abutment with a piston or the like, said flange at .one surface thereof intimately contacting with the periphery of the rod and at another surface overlapping one end face of said split ring, and said second ring having an integral portion deflected inwardly at the end opposite the said flange and overlapping the other end face of said split rin OSCAR W.
